What are fuel-cell electric vehicles and how are they different from EVs?

From established names like Tata Motors to new-age technology companies like Ather Energy and Ola, the automobile sector is shifting its focus to electric vehicles in view of an unprecedented rise in pollution levels and the climate change crisis therefore. The first breed of EVs to come out in the market are battery electric vehicles. Though good, these vehicles are not an alternative to the internal combustion engine, or ICE-based, vehicles simply because they have a limited range-per-charge capacity and are dependent on external charging systems. On that note, the Fuel Cell Electric Vehicles, or FCEVs as they are called, make a better alternative to ICEs-based vehicles.
